The problem of obtaining and rational use of whey proteins in human nutrition today is solved all over the world, traditional methods are being improved and new, more effective ways of processing milk whey, aimed at maximizing the withdrawal and use of its proteins, are being developed. The aim of the research was to develop the technology of albumin cheese ricotta from serum derived by the action of various coagulants. The raw material for cheese production was serum. For the study, two samples of cheese (with a threefold repetition) were made: Sample 1 - using serum formed during the fermentation of proteins with the participation of citric acid (normalized mixture + enzyme + citric acid); Sample 2 – using serum formed during protein mixing with the direct introduction of the fermentation culture (normalized mixture + enzyme + culture + calcium chloride). Determination of organoleptic and physico-chemical parameters in samples of albumin cheese, obtained from the developed technology, was carried out immediately after manufacture. The study of organoleptic characteristics of cheeses showed a similarity of indicators in samples 1 and 2. In particular, it was stated that pure, fresh taste and smell, with a specific albumin flavor, without foreign flavors and odors. Consistency in 1 sample was homogeneous, creamy, in 2 samples it was tender, but with a slight splinting. The color of the cheeses was white uniform throughout the mass. The lower acidity in the sample 2, which was at 17 °T, whereas in the sample 2 was higher – 20 °T. This, in particular, is explained by the use of citric acid for coagulation. The changes of microbiological parameters in the raw materials during storage, which consisted in the growth of the number of mesophilic anaerobic and optional aerobic microorganisms in two samples of cheese, were established. Given the permissible level of the number of mesophilic anaerobic and optional aerobic microorganisms in cheese not more than 1 × 105 CFU/g, the shelf life of two samples of cheese for 5 days. Indicators of titrated acidity during storage were correlated with changes in the number of mesophilic anaerobic and optional aerobic microorganisms. The mass fraction of moisture in the samples of cheese in the process of their storage decreased.

Rational use of grapes processing resources is among environmental problems of AIC of Republics of the North Caucasus and Krasnodar Territory. Currently, waste from grapes processing is not practically used and worsen the ecological state of environment. The research subject is a technology based on the production of cryo-powder from pulp, squeeze, seeds and grapes skin grown in the foothill and mountainous regions. The prerequisites for research were previously performed author works on related topics. The data on vacuum SHF-drying of grape raw materials and subsequent grinding in a cryomiller are given. Modes of preparation of grape raw materials and its subsequent dehydration and cryo-grinding, which provide the possibility of successful use in the dried state in the production technology of wine beverages, are proposed. The principal feature is the use of whole grapes as a raw material, with skin and seeds. Physico-chemical parameters, the content of phenolic substances and organoleptic characteristics of wine beverages made according to the traditional technology and the beverage made from grape cryo-powders are studied. A comparative assessment is made. It is established that vacuum SHF-drying contributes to better preservation of the properties of raw materials and finished products. The organoleptic assessment has shown that wine beverages developed according to the proposed technology had a more intense color and a more pronounced taste of sweetness and acid than traditional wine beverages. The advantage of this technology is the ability to transport grape cryo-powders in unregulated temperature conditions to any point close to the consumer and carry out the production of nutritional food there.

The integrated use of secondary raw milk is one of the most effective ways to optimize the processing of raw materials in the production of dairy products. The unique composition and properties of curd whey makes it a valuable industrial raw material that can be processed into a variety of foods and feed products. Nowadays, whey protein concentrates (WPC) are extremely popular with consumers. One of the promising areas of industrial processing of acid whey is the extraction of proteins by means of separate freezing (cryoconcentration). This process takes place at low temperatures (from 0 to minus 15°C), which makes it possible to preserve the composition and properties of the raw material, prevents denaturation of whey protein fractions, and preserves its valuable thermolabile components. The authors conducted laboratory tests of curd whey and WPC produced by several dairy companies. The research allowed the authors to determine the composition, sensory, physico-chemical, and microbiological properties of the samples. The research objective was to evaluate the sensory properties of the initial cheese whey and WPC obtained by cryoconcentration, to establish their chemical composition, as well as physico-chemical and microbiological parameters. The research also featured the effect of the whey acidity on the WPC output and the development of technological schemes of WPC production by separate freezing. All the samples of curd whey proved to meet the current standards and can be used for WPC production. The sample of laboratory-obtained WPC sample had 20.19% of dry substances and 12.80% of protein, which corresponds to the standard albumin with its 20.0% of dry substances. The titratable acidity of WPC did not exceed the permissible level of 95°T. The experimental results proved that the cryoconcentration technology produced concentrate that met the requirements of regulatory and technical documentation. The obtained data revealed an increase in titratable acidity from 47°T to 50°T during the storage of curd whey for 7 days. The increase in acidity increased the yield of WPC after 7 days of serum storage by 57.6%. The new WPC production scheme consisted of several stages: (1) the whey was obtained; (2) casein dust and dairy fat were excluded; (3) pasteurization; (4) two-stage cryoconcentration; (5) thermal coagulation of whey concentrate; (6) separation of WPC. The technology of cryoconcentrationcurd whey suggests designing industrial installations in-line type to obtain CSB.

Aim. To analyze the scientific and technical literature and identify ways to create a new generation of mass-consumption food products enriched with vital nutrients. Discussion. The main malnutrition of the Russian population is the excess of caloric intake over an indicator of the level of energy consumption. One of the ways to solve this problem is the production of functional food products or enriched functional products. The essence of this is that only those micronutrients that are really in short supply should be used in the fortification of products. These should be products of mass consumption, and especially those that undergo refining, which results in the loss of micronutrients. The use of raw materials and ingredients only of natural (animal, vegetable, mineral) origin, allows you to create active complexes that qualitatively change the physiological properties of the product, and can affect many product characteristics and processes such as physico-chemical, structural-mechanical and organoleptic characteristics of the product, the processes of color formation, fermentation, oxidation, storage capacity. However, sometimes a strong passion for enriching the product with useful macro- and micronutrients affects the taste characteristics. Conclusion. When developing recipes and technologies for new-generation products, it is necessary that the enrichment of the product with important and necessary elements does not worsen the organoleptic characteristics. At the same time, it is necessary to ensure the safety of products without compromising consumer properties. The diet should contain all the necessary nutrients (nutrients) for a person in sufficient quantities and balanced with each other in the most favorable proportions.

The main dysnutrition of the Russian population is the excess of caloric intake over an indicator of the energy consumption level. One of the ways to solve this problem is the production of functional food products or enriched functional products. The essence of this is that only those micronutrients that are really in short supply should be used in the fortification of products. These should be products of mass consumption, and especially those that undergo refining, which results in the loss of micronutrients. The use of raw materials and ingredients only of natural (animal, vegetable, mineral) origin allows creating active complexes that qualitatively alter the physiological properties of the product and can affect many product characteristics and processes such as physico-chemical, structural, mechanical and organoleptic characteristics of the product, the processes of color formation, fermentation, oxidation, and storage capacity. However, sometimes a strong passion for enriching the product with useful macro- and micronutrients affects the taste characteristics. Therefore, when developing recipes and technologies for new-generation products, it is crucial that the enrichment of the product with important and necessary elements should not deteriorate the organoleptic characteristics. At the same time, it is essential to ensure the safety of products without compromising consumer properties. The diet should contain all the nutrients necessary for a person in sufficient quantities and balanced with each other in the most favorable proportions

The authors study three fractions obtained as a result of hydrolysis of smoked sprat heads (under temperature of 130oC and presser of 0.25 MPa) – fat, protein water-soluble, and protein-and-mineral ones. Waste from sprat production of two fish canning complexes of the Kaliningrad Region - “RosCon” and “Kolkhoz for the Motherland” - was used as raw material. Hydrolysis was carried out in an aqueous medium in two ways - with preliminary separation of fat and without this operation. The protein fraction was sublimated and its quantitative and qualitative indices were examined - mass yield, solubility, chemical composition and molecular fractional composition of the obtained peptide fractions were determined. The output of sublimated protein fractions is practically independent of the type of raw material and the method of pre-treatment and is 6.47.9% of the mass of raw materials. The chemical composition of protein fractions varies widely in terms of fat (1.4–8.3%), minerals (9.8–13.4%) and proteins (72.1–80.2%). The solubility of the peptide fractions ranged from 91-98%. The molecular weight assessment results showed a high content of a low molecular weight fraction of peptides with an MM of less than 10 kDa in all experimental samples (about 38%). This indicates a high digestibility and biological value of the obtained peptide compositions. Sublimated peptide compositions had typical organoleptic characteristics, pleasant aroma and taste of smoked fish. Ключевые

In the present article the authors discuss the possibility of increasing of the suitability of milk as a raw material for cheese production through preservation of native properties of milk proteins, in the first place biologically complete whey proteins as well as the weight ratio of total and ionic calcium. For thermodynamic evaluation of the biosystem we used activation energy (Ea), chemical, physical and organoleptic characteristics. As a result: a methodology has been developed for determination of foodstuffs activation energy; it was determined that with increase in the proportion of the pectin introduced the activation energy and structuredness of the biosystem also increases, when the proportion of pectin is 0.5% the activation energy is 1.788 kJ/mol, when the proportion of pectin is 3% the activation energy is 2.241 kJ/mol, which means the increase by 25%; in the studied pasteurization standard, the maximum content of calcium is observed at 85oC and is equal to 133.8 mg%., in the control sample of milk the content of calcium is 130 mg%; addition of a complex food additive as a protector makes it possible to preserve native properties of the biosystem and guarantees formation of a denser protein coagulum which allows producing high-quality fermented milk products and cheeses.

The use of phytopowders as food additives allows you to create highly nutritious mixtures with a pronounced taste and aroma of fresh fruits and berries. Fruit and berry powders are already used in the production of jelly, fruit drinks, drinks, juices and sauces based on domestic plant raw materials with a high proportion of biologically active substances. The most important phytonutrients of sea buckthorn fruits (Hippophae rhamnoides L.) are carotenoids, flavonoids, anthocyanins, sugars, organic and amino acids, tannins and pectin substances, phospholipids, macro- and microelements. The aim of the research was to study the quality and nutritional value of freezedried sea buckthorn powder. Sublimated sea buckthorn was the object of study (TU 10.39.25-007-0111115841-2018) manufactured by IP A.N. Mazurina (Russia, Kaluga region, Borovsky district, Borovsk). The quality of packaging and labeling, as well as organoleptic characteristics, nutritional value and mineral composition of raw materials have been studied. It was determined that the marking of sublimated sea buckthorn does not comply with the regulated requirements of GOST R 51074-2003 and TR CU 022/2011. Organoleptic characteristics of phytopowder are identified as characteristic of this type of raw material. The actual protein and fat content of the test material does not correspond to the levels stated by the manufacturer. The studied raw materials are distinguished by a variety of chemical composition, namely, the content of protein, carotenoids, vitamins E and A, lipids, dietary fiber, unique trace elements – Al, Co, Cr, Cu, Fe, Li, Mn, Ni, Ti, Zn.

The purpose of the work was to investigate the effect of whey proteins and dry whey concentrates on the change of titrated and active acidity during digestion. In order to stabilize the consistency in the production of low-fat yogurts, dry whey was selected that met the requirements of State Standard 4552:2006. It is used to improve the taste of finished products, to add flavor, to improve the texture, as well as to improve overall quality. In addition, dry whey protein concentrate WPC 80 Milkiland was used. The addition of whey protein concentrate does not detract from the organoleptic characteristics of a normalized mixture, which allows it to be used in yogurt technology. The addition of whey proteins has a significant effect on the duration of gel formation. Whey protein concentrate and dry whey reduce the duration of latent fermentation and flocculation stages. The data obtained allows us to predict that they accelerate the coagulation process. This effect is enhanced by increasing the dose of protein concentrates. Conducted coagulation of milk with a different dose and observed changes in titrated and active acidity during the fermentation. Yogurt culture YF-L903, which includes Streptococcus salivarius subsp., Thermophilus, Lactobacillus delbrűeckii subsp. Bulgaricus were used for fermentation. The highest growth rate of titrated acidity is recorded for option 1 (0.5% dry sucrose) and controls that for 4 hours. the fermentation reached 80 °T. The highest rate of decline in active acidity is recorded in option 1 (0.5% dry sucrose serum). All samples for 4 hours of fermentation reached 4.65–4.72 units. pH. Thus, the acidity slightly increases with increasing the dose of serum protein concentrate and does not increase with the use of dry whey.

The leading direction in the field of nutrition is the creation of a range of products that contribute to improving health when they are used daily in the diet. The urgency of studying bovine colostrum-colostrum, which is an immune-modeling animal raw material, has been substantiated. Colostrum is a natural source of all the ingredients needed to build immunity. Biologically active substances contained in cow colostrum contribute to: restoration of immunity; restoration of the intestines and stomach; strengthening the nervous system; renewal of brain cells; improving emotional tone and mood; increasing vitality and performance; slowing down the aging process; protection against diseases of the intestines and stomach, cardiovascular system, respiratory tract, diabetes, allergies, osteoporosis and a number of other diseases. Colostrum contains a minimum of 37 immune factors and 8 growth factors that help the body fight disease and promote good health and longevity. The classes of immunoglobulins contained in colostrum, which represent the bulk of whey proteins, have been studied. Colostrum is a limited source of raw materials, its production period is short, there are many opportunities for industrial use, but due to the small amount of raw materials, the market remains undeveloped, with the exception of food additives. Taking into account the extensive therapeutic and medicinal properties of colostrum, its unique composition and properties, its composition and physicochemical properties were investigated, the fractionation parameters were determined using various systems. To process the experimental studies, the STATISTICA 12 software package was used. To obtain the regression equation, the matrix data were processed using the Microsoft Excel 2010 software package. The analysis of the data obtained indicates the possibility and prospects of using colostroma in food production technology.
